Despite making every effort to avoid it, Jack keeps running into new problems with minimization at the heart of the solution. Regular readers know that…
The manipulation of measurements in software has been a repeated source of problems for the software community. But this doesn't have to continue. Here are…
Not all systems have position or velocity sensors. In those cases, consider using a stepper motor to effect sensorless control. In my most recent columns…
High resolution encoders are expensive, but alternatives exist. You can develop a high-resolution system using a sinusoidal encoder or resolver. Last month, we covered some…
Increasingly, children's toys are embedded systems. The engineering behind them demands a closer look. Walk through any toy store (preferably unaccompanied by your children) and…
This month, Don wraps up techniques for determining angular position and turns the discussion to sensorless control. For some time now I've been writing about…
The fat lady hasn't sung yet, but she's warming up backstage. This month, Jack unveils part of his long-awaited minimizer. It's ironic, don't you think,…
Bingo! Months of agonizing produce an intellectual breakthrough. Can a quality minimizer be far behind? Boy, life does deal some crazy surprises, doesn't it? As…
